Catherine

Catherine is a feisty, sassy yet kindhearted Russian Blue cat. She is a driven, no-nonsense agent of M.E.O.W.S. who cares greatly for humans and also dislikes dogs till she met Diggs and Butch. She also seems compassionate when she listened to Diggs' backstory and loyal when she told Diggs that she wasn't going to leave him behind. In the end, when she was asked if she wanted to work with Diggs and the others she happily accepted, saying she couldn't say 'no'.
